FB/S3C2410: check default_display parameter passed in platform data

Ensure that the default display parameter passed in via the
device's platform data is valid. It turns out when mach-bast.c
was updated, the default_display was set outside of the display
array bounds, causing a panic on startup.

If the default_display is bigger than num_displays, then generate
an error and refuse to initialise the driver.
